This document is applicable to electrical insulating protective clothing used by skilled persons when they are working on or near live parts of low-voltage installations at nominal voltages up to 500 V AC.
The purpose of this clothing is to prevent dangerous current from passing through persons when there is a risk of unintentional contact with several live parts located in and around the working area.
This document does not deal with protection against the effects of an electric arc, DC applications and voltages higher than 500 AC.
The products designed and manufactured according to this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.

This document is applicable to portable ladders made only of non-conductive stiles, including accessories (pole leaning device, adjustable levelling device, adjustable ladder stabilizer, etc.) used to work on or near electrical systems and installations in the low voltage range (up to 1 000 V AC/1 500 V DC).
These ladders are used to provide temporary access, generally on overhead line structures, and to undertake electrical operations. They are expected to be used by one person only.
These ladders, in conjunction with other protective equipment provide sufficient insulation level to protect against inadvertent contact with live low voltage installations.
This document does not cover ladders used for live working on electrical installations at voltages above 1 000 V AC and above 1 500 V DC. These insulating ladders are separately covered by EN 61478.
This document does not cover products not made entirely with non-conductive stiles generally called mixed ladders. In this case the EN 131 series apply.
This document does not cover step stools, which are covered by EN 14183.
These ladders are only for specific professional use. Only skilled persons, after an appropriate training, can use this type of ladder for professional applications.
The products designed and manufactured according to this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the manufacturer instructions for use (where appropriate).
Annex E gives a rationale to explain how a ladder which fulfils the requirements of this document used with correct accessories gives better safety for the user than an ordinary ladder.

This standard is applicable to electrically insulating helmets used for working live or close to live parts on installations not exceeding 1 000 V AC or 1 500 V DC. These helmets, when used in conjunction with other electrically insulating protective equipment prevent dangerous current from passing through persons via their head.

This document is applicable to eye, face and head protectors used in work where there is a risk of exposure to an electric arc hazard. Such protectors consist of one or several devices (e.g. hood, goggles, balaclavas, face shields, helmets, etc.), which might need to be combined together in order to give protection to eye, face and head for the intended use. This document covers the performance requirements for protectors and single protective devices considering thermal, optical and mechanical hazards of an electric arc. Because of the limitations of test apparatus at very high energy arcs, no arc rating above 4 100 kJ/m2 (100 cal/cm2) can be assigned to protectors. This document does not cover protection against electric shock, noise, the consequences of physical and mental shock and the toxic influences caused by an electric arc. This document does not cover protectors for work intentionally using an electric arc, e.g. arc welding, plasma torch. This document does not cover face-screens for the reduction of an electric field inside conductive clothing in accordance with IEC 60895. Any other claims of the manufacturer for protection against other hazards to eye or face (e.g. welding radiation, hazards occurring during fire-fighting) are outside the scope of the document. Products designed and manufactured in accordance with this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.

This document defines methods to assess defects and to verify that products after the manufacturer process meet the requirements of the corresponding product standard.
The principles of assessment of defects for live working products are detailed in this document to assist product standard developers in prescribing the best means to achieve suitable quality of every finished tool, device and piece of equipment.
The following elements are not covered by the present document, but are included in each product standard:
- type tests;
- provisions and description for routine, sampling and acceptance tests;
- identification and classification of defects;
- risk analysis.
This document does not cover conformity assessment of commercial shipments or certifications.

IEC 61243-1:2021 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this document (see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B) and systems without neutral reference. For systems without neutral reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document contribute to the safety of users provided they are used by persons trained for the work, in accordance with the hot stick working method and the instructions for use.
Except where otherwise specified, all the voltages defined in this document refer to values of phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages are used to determine the operating voltage.
This third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage.
b) A contact probe is introduced as a new type of non-conductive contact electrode.
c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure.
d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded.
e) The marking for voltage detectors with low interference voltage has been made more precise.
f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added.
g) Requirements and tests for electromagnetic compatability have been implemented.
h) An example for good electrical connection for the tests is introduced.
